(A) General scheme of the Nt.BbvCl-inhibited, toehold-based DNA strand displacement strategies. (B) Real-time fluorescence changes upon treatment of the Nt.BbvCl-inhibition module i with variable concentrations of Nt.BbvCl: (a) 0, (b) 1, (c) 2, (d) 5, and (e) 10 units, [F2] = [Q3] = [I3] = 50 nM. (C) Real-time fluorescence changes upon treatment of the Nt.BbvCl-inhibition module ii with variable concentrations of Nt.BbvCl: (a) 0, (b) 1, (c) 5, and (d) 10 units, [F3] = [Q4] = [I4] = 50 nM.
